Hypersensitivity

Introduction Feeling an allergy is an increase in feeling due to a decrease in sensory threshold or a strong emotional factor. The clinical manifestation is that the patient's response to general intensity is particularly strong and sensitive, and it is unbearable. If you feel the sun is particularly glaring, the sound is particularly harsh, and the slight touch of the skin makes you feel painful. More common in the thalamus or peripheral neuropathy, psychiatry in neurasthenia, snoring, suspected, menopausal syndrome.

Cause

Causes:

Central or peripheral nervous system diseases such as spinal cord hernia, posterior root cord lesions, hypothalamic syndrome, ischemic neuritis, polyneuritis, trigeminal neuralgia, and neuralgia after herpes zoster. In addition, hypersensitivity can also be a manifestation of neurosis.

The clinical manifestation is that the patient's response to general intensity is particularly strong and sensitive, and it is unbearable. If you feel the sun is particularly glaring, the sound is particularly harsh, and the slight touch of the skin makes you feel painful. Hyperalgesia is most common. The distribution of the disease on the skin is often different due to different causes, which may be localized or systemic; it may be unilateral or bilateral. In the course of the disease, it may be temporary or permanent. Inflammation of internal organs such as cholecystitis, pancreatitis, appendicitis, and salpingitis often causes hyperesthesia in the skin area where the corresponding segmental nerves are distributed.

Differential diagnosis

Differential diagnosis of allergies:

The sensory disorder presents difficult and abnormal metamorphosis in the process of reflecting the individual attributes of the stimuli. Common sensory disturbances are:

1 feeling allergic. The ability to feel external stimuli is abnormally high.

2 feelings of loss and loss of feeling. The ability to feel external stimuli is abnormally reduced.

3 feels wrong. It gives a false impression of the nature of external stimuli.

4 internal sensibility discomfort. It produces a strange discomfort to the stimulus from the inside of the body.
